Earlier today (yesterday?) I posted about how comments work in Movable Type and how I wanted to let comment authors receive notification of replies to their comments. Feeling somewhat inspired by a suggestion from someone I started looking around at my options. In the end I decided to take a look at the MTThreadedComments plugin and see if I could figure things out from that. In the end it was pretty easy. I was able to cobble together version 0.1 in just a few hours. So, for people who are interested, you can now check out MTThreadMail. You can see the use of it in my comments currently. I'm willing to take comments and suggestions too, as this is my first time trying this. Also, this only works if you are running MTThreadedComments as the patch is based on that.
